SweepSteps class - gradients library

Constructors

SweepSteps.new({double softness = 0.0, required List<Color> colors, List<double>? stops, TileMode tileMode = TileMode.clamp, AlignmentGeometry center = Alignment.center, double startAngle = 0.0, double endAngle = math.pi * 2, GradientTransform? transform}): A Steps gradient differs from a standard Gradient in its progression from one color to the next. Instead of smoothly transitioning between colors, Steps have hard edges created by duplicating colors and stops.

Properties

asGradient → SweepGradient: Resolve these Steps to its smooth Gradient counterpart by colors and stops duplication, considering softness.
no setteroverride
asNill → Gradient: Available on Gradient, provided by the NillGradients extension
Gradient get asNill => nillify( /* this. */ runtimeType);
no setter
begin → AlignmentGeometry: Available on Gradient, provided by the GradientUtils extension
If this is a linear-type Gradient, returns this.begin. Otherwise the fallback retrun value is Alignment.center.
no setter
center → AlignmentGeometry: The color that correlates to stops entry 0 (the first color) is placed at AlignmentGeometry center, an offset into the (-1,-1) x (1,1) "paintbox" onto which the gradient will be painted.
final
center → AlignmentGeometry: Available on Gradient, provided by the GradientUtils extension
If this is a radial- or sweep-type Gradient, returns this.center. Otherwise the fallback retrun value is Alignment.center.

no setterinherited
steppedStops → List<double>?: Available on Gradient, provided by the GradientUtils extension
If this is a Steps-type Gradient, returns this.steppedStops. Otherwise the fallback retrun value is stops.
no setter
stops → List<double>?: A list of values from 0.0 to 1.0 that denote fractions along the gradient.

finalinherited
tileMode → TileMode: Available on Gradient, provided by the GradientUtils extension

Methods

animate({required Animation<double> controller, Map<GradientAnimation, dynamic> storyboard = const {}, GradientCopyWith overrideCopyWith = spectrumCopyWith}) → Gradient: Available on Gradient, provided by the GradientUtils extension
Returns the AnimatedGradient.observe animated Gradient output from a new AnimatedGradient constructed by this gradient and the provided parameters.
copyWith({double? softness, List<Color>? colors, List<double>? stops, TileMode? tileMode, AlignmentGeometry? center, double? startAngle, double? endAngle, GradientTransform? transform}) → SweepSteps: 📋 Returns a new copy of this SweepSteps with any provided optional parameters overriding those of this.
copyWith({List<Color>? colors, List<double>? stops, GradientTransform? transform, TileMode? tileMode, AlignmentGeometry? begin, AlignmentGeometry? end, AlignmentGeometry? center, double? radius, AlignmentGeometry? focal, double? focalRadius, double? startAngle, double? endAngle, double? softness, ColorArithmetic? shadeFunction, double? shadeFactor, double? distance}) → Gradient: Available on Gradient, provided by the GradientUtils extension
📋 Returns a new copy of this Gradient with any appropriate optional parameters overriding those of this.
createShader(Rect rect, {TextDirection? textDirection}) → Shader: Resolve these Steps to its smooth Gradient counterpart, then use that gradient's createShader() method.
inherited
lerpFrom(Gradient? a, double t) → Gradient?: Linearly interpolates from another Gradient to this.
override
lerpTo(Gradient? b, double t) → Gradient?: Linearly interpolates from this to another Gradient.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
scale(double factor) → SweepSteps: Returns a new SweepSteps with its colors scaled by the given factor. Since the alpha channel is what receives the scale factor, 0.0 or less results in a gradient that is fully transparent.
override
toString() → String: A string representation of this object.
override
withOpacity(double opacity) → Gradient: Returns a new Gradient with each color set to the given opacity.

Operators

operator ==(Object other) → bool: The equality operator.

Static Methods

lerp(SweepSteps? a, SweepSteps? b, double t) → SweepSteps?: Linearly interpolate between two SweepStepss.
